The New York Mets have officially unveiled their starting rotation for the 2026 season, beginning with their highly anticipated Opening Day matchup against the Pittsburgh Pirates on Thursday, March 26. The rotation, which will follow the typical five-man format, is set to feature a mix of established arms and rising talent. Notably absent from this lineup is veteran left-hander Sean Manaea, who instead will begin the season in a piggyback role—a decision that reflects both his recent struggles with injuries and his fluctuating performance over the last year.
The Opening Day assignment will go to Freddy Peralta, who had already been designated as the starter for the season opener. Peralta, a former Milwaukee Brewers standout, has been a consistent and dependable option in the Mets’ pitching staff, and his selection as the first pitcher to take the mound reflects both his durability and the team’s confidence in his ability to handle a high-pressure start. Following Peralta, the rotation will be comprised of David Peterson, Nolan McLean, Clay Holmes, and Kodai Senga. This combination of arms offers a mix of power, control, and experience, aimed at providing New York with a competitive edge in their early-season matchups. The news was first widely reported by Anthony DiComo, the Mets’ beat reporter for MLB.com, who confirmed the full composition of the rotation.
While the roster of starters features strong, versatile arms, Manaea’s absence as a conventional starter is the story grabbing attention. Rather than taking a traditional rotation spot, Manaea will be used in a piggyback capacity, a role in which he will share responsibilities with another pitcher during games. This approach is designed to ease the veteran into the season following a difficult 2025 campaign, during which he faced a combination of injuries and inconsistent performance. In 2025, Manaea appeared in only 15 games, registering a 5.64 ERA. He missed half of the season due to an oblique injury, which limited his ability to contribute fully and impacted his overall effectiveness on the mound.
Manaea’s Mets Tenure and Performance History
The Mets initially signed Manaea to a two-year contract worth $28 million ahead of the 2024 season. His first year with the team proved highly productive, as he demonstrated the skill and resilience that initially drew New York’s interest. During that season, Manaea delivered a 3.47 ERA across 32 starts while pitching a career-high 181.2 innings. He also secured 12 victories, marking the third time in his major league career that he reached double-digit wins in a single season. His performance confirmed that he was a valuable asset for the Mets, and in recognition of his contributions, the organization extended his contract to make him a $75 million player moving forward.
Unfortunately, Manaea’s 2025 season did not follow the same trajectory. He managed only 60.2 innings and his velocity declined after returning from the oblique injury. While he maintained an impressive 28.5% strikeout rate, the damage came when opposing hitters were able to make contact. Manaea allowed 13 home runs in those 15 outings, resulting in a career-worst 19.4% home run-to-fly-ball rate. This spike in long balls significantly inflated his ERA, even though advanced metrics like xFIP (3.30) and SIERA (3.07) suggested that his underlying performance was stronger than his surface stats indicated. Essentially, the home run rate was an outlier, and analysts expect some regression as Manaea continues to recover and adapt.
Manaea’s Career Journey
Manaea’s professional journey began in 2013, when the Kansas City Royals selected him with a competitive balance draft pick. Two years later, he was traded to the Oakland Athletics as part of a deal involving veteran infielder Ben Zobrist. Manaea made his major league debut with Oakland in 2016 and quickly became a fixture in their rotation. Over the following years, he faced interruptions from injuries, missing significant time in 2017, 2018, and 2019. Despite these setbacks, he consistently returned to form, proving himself as a reliable left-handed starter capable of handling a full workload when healthy.
Manaea’s versatility was first on display in 2025 when he shared the mound with Clay Holmes in a piggyback arrangement. This strategy emerged after both pitchers experienced late-season fatigue following strong starts. Mets manager Carlos Mendoza implemented the approach in hopes of preserving their arms and maintaining effectiveness deep into the season. The initial experiment was highly successful. On September 16, Holmes pitched four innings, allowing only two earned runs against the San Diego Padres, and Manaea followed with five innings of one-run ball, earning the victory. Subsequent attempts to replicate the success were less dominant, but the initial pairing demonstrated the viability of using Manaea in a hybrid role. This historical precedent likely influenced the Mets’ decision to employ the piggyback strategy once again to begin 2026.
Clay Holmes: From Closer to Rotation
Holmes’ career trajectory is notable for its shifts between starting and relieving roles. He began as a starter with the Pittsburgh Pirates in 2018 but quickly transitioned into the bullpen. Holmes emerged as a key closer for the New York Yankees in 2022, amassing 74 saves over three seasons. His success in relief highlighted his ability to dominate hitters in short bursts, a skill that translated well when he returned to the rotation with the Mets last season. Holmes started strong in 2025, posting a 2.97 ERA over the first three months. However, his effectiveness declined as the season progressed, and his strikeout rate fell to 15.9% from July onward. Despite the late-season dip, Holmes remains a highly valuable asset, both in the bullpen and as part of the team’s rotation strategy.
Opening Day Outlook and Team Strategy
The Mets’ decision to structure the rotation around Peralta, Peterson, McLean, Holmes, and Senga reflects a blend of strategy, experience, and calculated risk. Freddy Peralta’s role as the Opening Day starter underscores the team’s confidence in his ability to lead from the mound. David Peterson and Nolan McLean bring a combination of control, command, and potential upside, while Kodai Senga adds international experience and the ability to deliver high strikeout totals. Holmes’ dual experience as both starter and reliever provides flexibility, especially in tandem with Manaea in the piggyback role.
Using Manaea in this capacity allows the Mets to protect his arm, manage his innings, and potentially maximize his effectiveness across the season. Given his past injury history and the inconsistencies of 2025, this conservative approach is a calculated move designed to optimize performance without overexposing the veteran lefty.
The piggyback strategy—where two pitchers share responsibilities in a single game—has grown in popularity across the league as teams seek to extend pitcher longevity while maintaining effectiveness. In Manaea’s case, the system offers several advantages. It mitigates the risk of overuse, reduces the likelihood of fatigue-related performance declines, and allows the coaching staff to match pitching styles against opposing lineups more strategically. The 2025 experiment with Holmes demonstrated that when executed correctly, the approach can lead to victories while keeping arms fresh for the long season.
As the Mets head into the 2026 season, their rotation appears well-balanced. Peralta provides stability and leadership, Senga offers strikeout capability, and the inclusion of Holmes and Manaea in a piggyback tandem ensures flexibility. The mix of veteran experience and younger arms like McLean and Peterson gives New York depth and adaptability, which will be crucial as the season progresses and injuries or fatigue inevitably impact the roster.
Manaea, in particular, will be a storyline to watch. After a turbulent 2025 campaign, he enters the season with an opportunity to reset and prove his worth in a controlled, strategic role. If the piggyback approach works as intended, the Mets could benefit from effectively having two pitchers for the price of one inning, allowing for higher overall effectiveness across the early months of the season.
The Mets’ rotation for Opening Day 2026 reflects careful planning, a recognition of past challenges, and a proactive approach to pitcher management. By starting Freddy Peralta on the mound and employing Manaea in a piggyback role alongside Clay Holmes, the team balances immediate performance needs with long-term health considerations. Meanwhile, the inclusion of Peterson, McLean, and Senga rounds out a rotation that combines youth, experience, and international talent. Fans can expect a strategic season for the Mets’ pitching staff, with early games providing insight into how these decisions will pay off.
Sean Manaea’s role, in particular, embodies both a cautious approach and a vote of confidence: the Mets clearly value his talent and want to ensure he can contribute meaningfully over the long season, even if that means starting in a nontraditional role. Meanwhile, the rest of the rotation provides solid support, and the Opening Day matchup against the Pittsburgh Pirates will offer the first glimpse of this new pitching structure in action. As the 2026 campaign unfolds, all eyes will be on Manaea, Holmes, and the supporting rotation to see whether the Mets’ strategy translates into success on the field.
